Smart People Share Senseless Ideas That Can Be Proven Mathematically[rebelmouse-image 18356273 is_animated_gif=
Math was never really my strong suit, but I do understand that some stuff just needs numbers to make sense. Not sure what I'm talking about? Leave it to Reddit to explain it way better than I ever could. One Reddit user asked:
What are some things that make no sense but can be proven mathematically?
I'm still not 100% sure of the math that goes into explaining why one pizza might be more pizza than two pizzas or why straws don't work in the moon - but I feel like if SpaceForce is going to be able to do SpaceLunch these are just bits of knowledge we all need to have. Prepare to have your mind blown by stuff that makes little-to-no sense in the real world, but math says is perfectly normal.
The Perfect Sphere[rebelmouse-image 18360101 is_animated_gif=
The Banach-Tarski paradox is a nice example of something that exists because of mathematical objects that have no correspondence in reality. If you have a mathematical perfect sphere and cut it in ways that are only possible in mathematics (single points do not exist in reality), you can rearrange it to get two spheres. And that is just one example of what messing with infinity can give you.
The great Polish sci-fi writer Stanislaw Lem in his book "Summa Technologiae" wrote that mathematics is like a mad tailor, making all possible sorts of clothes. Some of them fit humans, some fit trees or octopi, some fit creature that exist but we haven't met yet; and some just don't fit anything in our universe. Mathematics makes theories that seemingly have no point in physical reality; that might be so, or it might be that we just haven't discovered a way to apply them. Number theory was thought to be useless until cryptography came along.
Monty Hall[rebelmouse-image 18360102 is_animated_gif=
The Monty Hall problem's solution doesn't make sense until you start adding tens or even hundreds of doors.
Here's my attempt:
3 doors: 1 goat, 1 car, 1 nothing. Your chances are 1/3 to choose the car, yes? There are still 3 doors.
3 doors, goat is shown. 2 unknowns. There are still 3 doors- your original probability DOES NOT CHANGE because of this. It's still 1/3 chance. This is the part where I got stuck before. There are still 3 doors, your chances are 1/3.
Acting on the information though by swapping ADDS the 1/3 chance by knowing it has a goat behind it will ADD the probability together. 1/3 and 1/3 together. Making 2/3. The important part is acting on the information. However, if you had no outside knowledge, aka if your friend comes after a door is opened, his chances are 1/2 because he doesn't know. By opening a door for you, the dude 'adds value' to the door that isn't chosen by you but not to the one chosen by you originally.
So another way of thinking of it is NO MATTER WHAT choice you had made originally, you had 1/3 chance of winning. What's left is 2/3 right? If you abandon your original choice and jump ship to the other pool, your chance doubles.
How Much Rope?[rebelmouse-image 18346795 is_animated_gif=
The old rope-around-the-earth trick.
Imagine you have enough rope to go all the way around the earth's equator (ignoring mountains, etc). Now assume that you'd like to have that rope be 1 meter off the ground all the way around the earth. How much rope would you have to add?
A New Deck Of Cards[rebelmouse-image 18360103 is_animated_gif=
If you take a deck of new cards and shuffle it, chances are good that's the first time that sequence has ever existed on earth. 52! Is a long number.
No Straws On The Moon[rebelmouse-image 18360104 is_animated_gif=
This is less math and more physics, but straws don't work if they're taller than a very certain height - and they don't work at all on the moon. In order for liquid to flow through a straw, the inside of your mouth needs to be at a lower pressure than the outside air. If there is no outside air (like, say, on the moon for example) your mouth can't be at any lower pressure.
Pizza Math[rebelmouse-image 18360105 is_animated_gif=
One 18" pizza is more pizza than two 12" pizzas. One 17" pizza is almost exactly two 12" pizzas by area. However, the two 12" pizzas will still have about 30% more crust than the 17" pizza. So if you're going stuffed crust, go small.
Global Temperature[rebelmouse-image 18360106 is_animated_gif=
When I was in uni, we had a calculus temp/sub prove that the temperature here and a spot exactly on the opposite side of the earth, are the same.
If I recall correctly, he took 2 classes to write it on many many chalkboards. We were mostly in awe of his handwriting, and later found out he was allowed to turn in his thesis in handwriting, rather than typewritten. Before anyone questions, his thesis was not what he burned our time with.
It is the Borsuk-Ulam theorem in topology: for a continuous mapping of a sphere onto a plane, there will be two points which were antipodal on the sphere and are the same point on the plane. In fact, we can pick two continuous variables here: say, temperature and atmospheric pressure. Then it is a mapping between the Earth's surface and a temperature-pressure plane, so there will be two antipodes that have the same temperature and atmospheric pressure.
Happy Birthday![rebelmouse-image 18348437 is_animated_gif=
The birthday paradox.
Get 23 (randomly chosen) people in a room. It is decently likely that 2 of the 23 people share the same birthday (discounting year).
I am a mathematics graduate, I understand the mathematics, yet there's still a part of my brain that is thrown by this logic!
For anyone intrested: the idea is how many times you compare 2 peoples birthday or, in other words, how many unique parings of birthdays you have. The first person has 22 people to compare their birthday to, 2nd one has 21, therefore you have 22+21+20....+1=253 unique parings. Chances of a pair to be identical is 1/365 (disregarding leap years):
(1-1/365)^253=0.4995 or about 50%
The Speed Of Light[rebelmouse-image 18360107 is_animated_gif=
Light moves at the same speed for everyone.
If you're moving away from the light, or moving towards it, doesn't make a difference, it's still travelling the same speed for you
Roulette[rebelmouse-image 18360108 is_animated_gif=
Gambler's fallacy - patterns of independent events do not dictate future results. I know it is true but still fall for it.
When a fair roulette table lands on black 10 times in a row it is just so tempting to keep putting money on red.
The first time we all have sex is such a nerve wracking experience.
Everybody wants to be good. No... GREAT!
That probability is highly unlikely though.
There is so much to learn and navigate when it comes to sex.
RedditorBobirrrwanted to talk about the birds and the bees and all the information that surprised us. They asked:
"What did you not know about sex until you lost your virginity?"
GuidesBaseball Fail GIFGiphy
"You gotta guide it much more than you think."
"Just because you’re having sex doesn’t mean you’ll become good at it without a remarkable amount of trial and error."
"More than trial and error, you gotta ask your partner how it was, what they liked and didn’t like and what they want to try. Being able to have an open and honest conversation about sex with your partner makes it so much better."
"Agreed. An ex friend of mine boasted that he was great in bed because his body count was over 50. Bro, if your body count is that high at that age, it means no one’s coming back for more."
"When you have that mindset you won’t ever get the chance. It’s not that big of a deal and not something you need to put that much pressure on that you’re fretting about it like this. It’ll come, just be you and don’t sweat about it. I was 21 when I lost my virginity and all my friends were 15-18 when they lost theirs. I don’t regret when it happened and I don’t feel like I was late or missing out, it just happened when it happened."
"That two bellies rubbed together at just the right angle can make a loud fart noise. Funny tho when it does happen for the first time."
I hate that noise. Gross. It's confusing.

"How you pleasure yourself can be a huuuge influence on your sex life."
It'a All New
"Instead of just after virginity, after years of having sex and looking back at my first time where my partner was much more experienced than me, I’ve realised that pretty much all sex with a new person, virginity or not, feels new. I was really hung up on being good at it when I should’ve treated it as a learning experience for the next time."
Too Much Porn
"That foreplay is SUPER important. You don't see it too much in a lot of porn so until you get into the bedroom you don't really consider the prep. Often times you just see people going at it which is great and all but everything is much better when both parties are warmed up."
It makes sense...
"That I was allergic to latex."
"Same. Friends would talk about having sex multiple times a day, and I was over here wondering WHY they would ever put themselves through that. It took days to recover. Someone finally mentioned a latex allergy, and it all made sense."
"Omg this. Except my allergy was fairly mild. It meant peeling skin a couple days later. Literally took me years to find out why that was."

America is in quite a state right now.
We are hurting in ways we've never hurt before.
And getting better doesn't seem like an option on the horizon.
America gets a lot wrong everyday.
But, maybe let's try to focus on what America does right.
Maybe it can be a little comfort in times of struggle.
People from all over the world want to live here.
Redditor Ulrich-Stern wanted to discuss the best of America. They asked:
"What does the United States get right?"
I think America certainly has a strong work ethic. We know how to work and win.

"Accessibility code for buildings. I come from a country where disability is looked upon like a crime or fault. USA does an amazing job making things accessible. I haven’t seen all of USA but majority of the places has amazing system."
"Our public libraries are a real backbone for the country."
"Andrew Carnegie's groundwork in building the institution of free libraries, even in small towns, set a precedent that we wouldn't fathom today but couldn't live without. They often serve not only as an information exchange but as cultural hub, art gallery, performing arts center, tax aid, voter registration, job resources, etc. in communities."
"Plus they're one of the only places you can just exist for hours indoors without the expectation you must buy something.And I feel like they've adapted to the ever-changing needs of their patrons in modern times faster in the US than most places."
"'A library outranks any other one thing a community can do to benefit its people. It is a never failing spring in the desert.' -Andrew Carnegie"
'restore' or 'create'
"Valuing actual wilderness in places like national parks. Here in England, they will 'restore' or 'create' natural habitats, which is sort-of nice, but they are almost like zoos. They are too small to survive by themselves so they are actively maintained."
"And in some English national parks, they actually allow housing developments as long as the architectural design is sympathetic. Here, 'countryside"'means farms. There is still a notion in the USA of protecting some large wilderness areas from development."
"The rate of smoking cigarettes. We do very little well in the US when it comes to overall health, but we are light years better than most places when it comes to the prevalence of cigarette smoking. Hardcore anti smoking adds + laws of inconvenience + social stigma really did work."

"Films. Don't get me wrong, the US can put out some bad films, but the best ones I've seen are usually American."
We do do films well. That is a big plus.
FamilyKids Playing GIF by moodmanGiphy
"The United States adopts more children than the rest of the world combined."
"Burgers. Motherfreakin' burgers."
"I'd expand that to sandwiches in general. Burgers, Philly cheese steaks, Reubens, subs, clubs, chopped cheese, po'boys, just this whole sandwich spectrum. Americans just took sandwich concepts from across the globe and ran with them."
"I've always envied your wildlife. I'm from England and the only large wild animals (other than fish) we have are deer, boar and foxes. And they're incredibly rare. I've always thought it was so cool one country could have bears, moose, cougars, alligators, panthers, bison/buffalo, etc."
"Gas stations like QuikTrip, where they have clean bathrooms, lighted parking lots, free air for your tires, ten different coffees on tap, beer, hotdogs, any soft drink or snack you want, the list goes on. In other countries -- you're not gonna believe this -- their gas stations only sell... gas."

"The US is an absolute science powerhouse. The technology we come out with has touched the lives of nearly every person on the planet."
"I say this as an immigrant who came to this country, so perhaps take it with a grain of salt. But it truly gives people a second chance at life. My life would be nowhere near as good as it is right now if I were back in my home country."
Maybe America isn't the hot mess a lot of people think it is. We'll see...
Sex is an important part of life.
That is just a fact.
But sex is also about connection and intimacy.
So it's not a surprise when many relationships take a hit after the sex dries up.
It's not something to ignore.
It's the biggest problem in the world, but partners should discuss it.
RedditorItsyBitsyJoxywanted to hear about reasons to stick around with a partner when there is no sexy time. They asked:
"Would you be in a sexless relationship? What circumstance would you find acceptable for this?"
Sex is fun. And when the sex stopped in my relationships... so did the fun. But that is just me.

"I'm over 80."
"There’s a lot of people that are going to be real shocked once they hit their 70s."
"Our second child has ruined her sex drive. Intimacy is still there but extremely infrequently. I've learned how much that intimacy brings to the relationship, it feels very lonely and although I know it's not her fault, it can still make you feel like she's not attracted to me anymore. It can be pretty lonely too if you go from a romantic relationship to borderline platonic one. You can't help wonder how much is body changes and how much is you."
"I had rectal cancer and because of the surgery I can no longer get an erection, it's very lonely."
"Not sure if one exists, but a site to just make friends to be cuddle buddies, or whatever, should exist for people like you & me. I lost my sex drive & would like a relationship for that occasionally."
"In my case, it's not wanting to see someone very often, as well as the lack of sex drive, that I think would make it difficult. I also don't like people over to my home as it's too small for a couch & we'd be hanging out on my bed, which is weird to me."
"I'm in one now. My husband had a stroke... no sex is not the big problem for either one of us."
"This comment brings a lot of perspective. My gut reaction to this question was no. Sex was and still is pretty significant in my relationship with my wife. We’re in our 30’s and have been together over a decade. But if something happened to her and it was no longer an option? I would never leave her and love her too damned much to imagine it, no matter how much we love sex."

"I have a near sexless marriage. The love is strong, but the desire is one-sided. That hurts."
Sexless over loveless is definitely easier. So there is that.
Over time...up s GIFGiphy
"I am happily married to my good lady for decades and decades. There are times when it has been sexless for whatever reason but never has it been loveless.I wouldn’t have lasted 2 days in a loveless relationship."
You play the cards you are dealt
"I’m dating a man who got diagnosed with prostate cancer a year or so into our relationship. Prostate had to come out and it’s a hit or miss whether or not sexual function comes back. In his case, it was a miss. He wanted me to move on because he got very depressed over it."
"He’s so pleasant and a real decent human being so I stayed with him. Who would abandon someone due to a health crisis? Unfortunately he got bladder cancer next so this is another hurdle to go over. You play the cards you are dealt. We are together in this."
"The reasons for the 'sexlessness' and the depth of the relationship are key factors. My wife got breast cancer at 40 and while she lived another 8 years, the chemotherapy nullified her libido and made intercourse impossible. And yet I dearly wish we could have grown old together whether or not this would have changed. But that’s completely different from cohabiting a loveless marriage or even facing such a situation in one’s youth only a few years after marriage. That would be hard."
"A sexless relationship is better than a loveless relationship, as long as I'm loved and we share physical affection like cuddling and kisses and I'm allowed to beat my meat when I need too I wouldn't care. Just a heads up to all the people who take this personally enough to comment how wrong I am."
"There's no such thing as a wrong option, my opinion is in regards to myself and myself alone I'm not answering for anyone else. Different opinions aren't wrong... OP asked a question to be answered from your own point of view..so there's no reason to call anyone else wrong... it's about you, answer for YOU I've answered for me."
Love is there...Checking In I Love You GIF by Seize the AwkwardGiphy
"I'm in one. Not happy about it, but love is still there so that's nice."
"Same. Maybe had it once in the last 12 years. Finally decided to go to couples/sex therapy this year. Not sure it is helping, but at least I finally brought up that I wanted to try something. My wife is my best friend and I love here with every fiber, just wish there was more intimacy there."
it never happens...
"We haven't had sex in five months due to numerous reasons. Never have alone time with my mom and daughter here. We're both too tired. Our bed we have sex on is where my mom is sleeping. Our waterbed is difficult to use. We always say next weekend and it never happens. We're still going strong though. We love each other and that's what matters."
Well I guess some people can make it work. More power to you.
We all have things which get on our nerves.
Some people have a fairly high tolerance level, and are only truly perturbed by things which are beyond the bounds of common decency, or which are universally accepted as annoying or inconvenient.
Others are not so lucky, and tend to be set off by things which might go completely unnoticed by everyone else.
Redditor Onatic420 was curious to learn the things which instantly make others want to pull their hair out and scream, leading them to ask:
"What do you find annoying as f*ck?"

For your sake, and everyone else's.
